The HP sceme in the patent refers to an array of series and parallel
diodes to reduce noise.

Just paralleling them does not reduce the noise!

The 4 paralleled in the 5065  are to give enough phase deviation for the
low modulation level applied.  (150mv)

The symptom was a fluctuating 2nd harmonic meter reading and coresponding
fluctuations at the A7 TP2 test point.

John I could not see the info you refered to?
